1 and 1/2=1+1/2=2/2+1/2=3/2

3 and 1/2=3+1/2=6/2+1/2=7/2

3/2dozen=7/2cups
times 2 both sides
3dozen=7cups
divide by 3 both sides

Using proportion,

If Out of 550 calculators = 6 are defective,

Then out of 12000 calculators = ? are defective

$\frac{12000 calculators}{550calculators} * 6$

= 21.8 * 6

= 130.8 ≈ 131

∴ Approximately 131 calculators are defective

Which equation shows a line with a slope of 3 that passes through the point ((1,-2)

qaws [65]

Answer:

y = 3x - 5

Step-by-step explanation:

Slope m = 3

Using (1,-2)

Slope-intercept: y = mx + b

-2 = 3(1) + b

-2 = 3 + b

b = -5

Given m||n, find the value of x.<br> 135

Viefleur [7K]

Answer: Option C.

Step-by-step explanation:

Let as consider the complete question is same as question shown in the below figure.

In the figure m║n.

If a transversal line intersect two parallel lines then same sided interior angles are supplementary angles and their sum is 180 degrees.

$3x+x=180^{\circ}$

$4x=180^{\circ}$

Divide both sides by 4.

$x=\dfrac{180^{\circ}}{4}$

$x=45^{\circ}$

The value of x is 45 degrees.

Therefore, the correct option is C.
